OPERATION TROUBLES AND ACTIONS DISCHARGED BATTERY 0. When checking or handling the battery, stop the engine and turn the starting switch key to the OFF position. The battery generates hydrogen gas, so there is a haz- ard of explosion. Do not bring lighted cigarettes near the battery, or do anything that will cause sparks. Battery electrolyte is dilute sulfuric acid, and it will attack your clothes and skin. If it gets on your clothes or on your skin, wash it immediately off with large amounts of water. If it gets in your eyes, wash it out with fresh water, and consult a doctor. When handling batteries, always wear protective gog- gles and rubber gloves.

When removing the battery, first disconnect the cable from the ground (normally the negative (-) terminal). When installing, install the positive (+) terminal first. If a tool touches the positive terminal and the chassis, there is danger that it will cause a spark, so be extremely careful. If the terminals are loose, there is danger that the defective contact may generate sparks that will cause an explosion. When removing or installing the terminals, check which is the positive (+) terminal and which is the negative (-) terminal. Green rust around the terminals is a cause of self-discharge of the battery. Polish the terminals with sandpaper.

After removing the rust, coat the terminals thinly with grease before installing. Battery Removal And Installation 0. NOTICE After securing the battery, check that it does not move. If it moves, tighten it again securely. Before removing the battery, remove the ground cable (nor- mally connected to the negative(-) terminal).
